EMD GP40 - Union Pacific® #864

Widely recognized as one of the most successful 4-axle diesel locomotives to operate in North America, the GP40 entered production at EMD’s La Grange, Illinois plant in 1971. Gaining popularity among railroads for its reliability and ease of maintenance, the GP40 remained in EMD’s catalog until 1986, when the final Dash 2 variation was delivered. Today, GP40 series locomotives remain crucial to the switching and branch line needs of class one railroads, with many additionally providing service for short lines and industrial operators. The Bachmann Large Scale GP40 arrives in 1:29 scale with realistic details, directional headlights and marker lights, a non-proprietary plug-and-play circuit board for the control system of your choice, and four authentic paint schemes.
